Removing old instance and reinstalling RRS feed

  • Question

  • I have been trying to uninstall a previous installation of SQL server without success.  I have tried to uninstall every mention of SQL on my machine and they are all still visible in the App & Features menu.  I have tried to repair the program and overwrite with a new installation but nothing seems to work.

    If uninstall went without error, they still might be visible but that does not mean that the files are still present. Can you run discovery report and post output here.

    This should be better handled by Microsoft just so that people do not confuse themselves.

    Rest assured there is NO instance of SQL Server out their, what you are seeing is just the icons or options their, and do not be bothered about it. As i said MS should be little more cautious on this and remove the options as well

    There is nothing  report, but it still exists under the windows panel, indicating that the software has not been completely removed. 
    Please try the following steps:

    1.Delete Microsoft SQL Server folder(C:\Program Files);
    2.Delete Microsoft SQL Server folder(C:\Program Files (x86));
    3.Delete the registry, win + R open and run, enter Regedit, press Enter to run, the registry editor will come out,
    3.1:Delete the Microsoft SQL Server folder under HKEY_LOCAL_MACHINE—SOFTWARE—Microsoft, and these items are
    (Microsoft SQL Server,Microsoft SQL Server xxxx Redist,Microsoft SQL Server Local DB,Microsoft SQL Server Native Client xx.0)
    3.2. delete all Microsoft SQL Server folders under HKEY_CURRENT_USER—Software—-Microsoft, and the item is(Microsoft SQL Server)
    4.Restart your computer and then check.

    Best Regards.

  • I do not want to post unnecessarily but suggesting to remove Reg keys even when discovery report shows nothing is dangerous. A newbie should never be recommended to fiddle with registry. Again what he is seeing is perfectly normal and their is no need to remove any reg component
